Ingredients

Dry Ingredients

2 tablespoons coconut flour
2 teaspoons baking powder
¼ teaspoon salt

Wet Ingredients

6 large eggs, separated
225 g (8 oz) cream cheese, softened
100 g powdered erythritol or monk fruit sweetener
60 g (¼ cup) melted unsalted butter
1 teaspoon vanilla extract
1 teaspoon lemon zest (optional)
½ teaspoon cream of tartar

Optional Frosting

250 ml (1 cup) heavy whipping cream
2 tablespoons powdered keto sweetener
½ teaspoon vanilla extract

Optional Garnishes

Fresh raspberries
Fresh blueberries
Toasted sliced almonds
Unsweetened coconut flakes
Sugar-free white chocolate shavings
Lemon zest
Fresh mint leaves

Equipment

Two large mixing bowls
Electric mixer or stand mixer
Fine sieve
Rubber spatula
20 cm (8-inch) round cake pan
Parchment paper
Cooling rack

Preparation Time

Preparation: 25 minutes
Baking: 35–40 minutes
Cooling: 45 minutes
Total Time: About 1 hour 50 minutes

Step 1: Prepare the Oven

Preheat the oven to 170°C (340°F).

Grease the cake pan lightly with butter or oil.

Line the base with parchment paper to prevent sticking.

Step 2: Combine the Dry Ingredients

In a medium bowl, whisk together:

Almond flour
Coconut flour
Baking powder
Salt

Sifting the dry ingredients helps remove lumps and creates a finer cake texture.

Step 3: Prepare the Egg Yolk Mixture

Place the egg yolks into a large mixing bowl.

Add:

Cream cheese
Melted butter
Powdered keto sweetener
Vanilla extract
Lemon zest (if using)

Beat for about 3–4 minutes until smooth, creamy, and pale in color.

Gradually mix in the dry ingredients until fully incorporated.

Step 4: Whip the Egg Whites

In a separate clean bowl, add the egg whites and cream of tartar.

Using an electric mixer, beat until stiff peaks form.

The egg whites should be glossy and hold their shape without collapsing.

This step is essential for achieving the cake’s signature cloud-like texture.

Step 5: Fold the Batter

Using a rubber spatula, gently fold one-third of the whipped egg whites into the almond flour mixture to lighten it.

Gradually fold in the remaining egg whites in two additions.

Use slow, sweeping motions from the bottom of the bowl upward.

Avoid stirring vigorously, as this will deflate the air incorporated into the egg whites.

The finished batter should be light, fluffy, and airy.

Step 6: Transfer to the Pan

Pour the batter into the prepared cake pan.

Smooth the top gently with a spatula.

Tap the pan lightly on the counter once or twice to remove any large air pockets.

Step 7: Bake

Bake for 35–40 minutes, or until:

The top is lightly golden.
The cake springs back when gently pressed.
A toothpick inserted into the center comes out clean.

Avoid opening the oven during the first 25 minutes, as sudden temperature changes can cause the cake to sink.

Step 8: Cool

Remove the cake from the oven.

Allow it to cool in the pan for 15 minutes.

Carefully transfer it to a cooling rack and let it cool completely before frosting or serving.

Step 9: Prepare the Frosting

In a chilled mixing bowl, combine:

Heavy whipping cream
Powdered keto sweetener
Vanilla extract

Beat until medium to stiff peaks form.

Spread or pipe the whipped cream over the cooled cake.

Step 10: Garnish

Decorate with your preferred toppings, such as:

Fresh raspberries
Blueberries
Toasted almonds
Unsweetened coconut flakes
White chocolate shavings
Lemon zest
Mint leaves

Serve immediately or refrigerate until ready to enjoy.

Storage

Store the cake in an airtight container in the refrigerator for up to 5 days.

Bring it to room temperature for about 15 minutes before serving for the best texture.

Freezing

Wrap individual slices tightly in plastic wrap and place them in a freezer-safe container.

Freeze for up to 3 months.

Thaw overnight in the refrigerator before serving.

Delicious Variations

Chocolate Cloud Cake

Add 2 tablespoons unsweetened cocoa powder to the dry ingredients for a rich chocolate flavor.

Lemon Cloud Cake

Increase the lemon zest to 2 teaspoons and add 1 teaspoon of fresh lemon juice to the batter for a brighter citrus taste.

Coconut Cloud Cake

Replace 30 g (⅓ cup) of the almond flour with unsweetened coconut flour and sprinkle toasted coconut over the frosting.

Almond Vanilla Cake

Add ½ teaspoon almond extract along with the vanilla extract for a deeper nutty aroma.

Berry Cloud Cake

Layer the cake with whipped cream and fresh raspberries or strawberries for a refreshing summer dessert.

Mocha Cloud Cake

Mix 1 teaspoon of instant espresso powder into the batter for a subtle coffee flavor.

Cinnamon Spice Cloud Cake

Add 1 teaspoon ground cinnamon and a pinch of nutmeg to the dry ingredients for a warm, comforting variation.

Tips for Success

Use room-temperature eggs and cream cheese for a smoother batter.
Whip the egg whites in a completely clean, grease-free bowl to achieve maximum volume.
Fold the egg whites gently to preserve the air that gives the cake its fluffy texture.
Use finely ground almond flour rather than almond meal for a lighter crumb.
Do not overbake, as keto cakes can dry out more quickly than traditional cakes.
Cool the cake completely before frosting to prevent the whipped cream from melting.
Store leftovers chilled to maintain freshness and texture.
